Abstract: FIELD: chemistry. 
     SUBSTANCE: invention relates to environmental protection and can be used for treatment of effluent, drainage and over-slime water with increased salt content. Contaminated industrial water is subjected to successive primary purification from mechanical impurities, electroflotation purification, ultrafiltration, reverse osmosis desalination of the first stage, reverse-osmosis desalination of the second step over the permeate and final purification from ammonium ions. Primary purification of contaminated water from mechanical impurities is carried out using hydrocyclone 3, after which coagulation is performed in tubular coagulator 8. After ultrafiltration, water is subjected to two-step ozonation in labyrinth columns 17, 18. Concentrate obtained at the first stage of reverse-osmosis desalination 37 is subjected to reverse-osmotic desalination of the second step by concentrate 41, and the permeate obtained at that second step is returned to the first stage of reverse-osmosis desalination 37. Final purification of water from ammonium ions is performed by means of filling filter with zeolite.

Abstract: A force transducer, particularly for the ballistic measuring of the combustion pressure in the cartridge case of a firearm, is disclosed which includes a force transmission element which rests with one of its front areas on the cartridge case. The force transmission element is surrounded on its exterior by an outer sleeve which also rests with its front area on the cartridge case. The front areas of the force transmission element and of the outer sleeve are exactly adapted to the curvature of the cartridge case by reaming after the transducer has been mounted in the firearm. With the combustion of the powder, the cartridge case expands and transmits its force to a sensor element via the force transmission element, with the sensor element being preferably in the form of at least one piezoelectric transversal quartz element which is held under pretension between the force transmission element and a basic receiver component. The spring rigidity of the force transmission element and the spring rigidity of the outer sleeve are matched in such a way that both parts yield essentially to the same extent to the pressures acting upon them in the axial direction of the transducer. The result is that the contact conditions of the cartridge case with the front area of the force transmission piston do not change appreciably after the expansion in comparison with the initial conditions so that a calibration curve of the force transducer which is independent of the installation can be supplied by the manufacturer.
